Answer:
As law of sin:
CD/sinE = DE/sinC
Then
12/sin83 = 5/sinC
Then
sinC = 5*sin83/12 = 0.413
Then
C = arcsin(0.413) = ~24.4 deg
Then
D = 180-C-E = 180-83-24.4 = ~72.6
Hope this help, bro!

Answer:
X=57
Step-by-step explanation:
77+46+X=180
123+X=180
X=180-123
X=57
The focus is left of the vertex, so the parabola opens to the left. The vertex is halfway between the focus and directrix, so the directrix is the vertical line
x = 2
Answer:
x = 
7
Step-by-step explanation:
= 49
can equal 7 or -7
